Determine the amount in an account after 18 months if 10000 is deposited in a savings account paying 1.6% interest compounded quarterly

$10,242.41

Step-by-step explanation:

To calculate amounts with compounded interest, we use where

-A is the total amount int he account after interest

-P is the principal or starting amount

-r is a decimal conversion of the percentage rate

-n is the number of times compounded a year

-t is the number of years

For this account, P=10000, r=0.016, n=4 for 4 quarters in a year, and t=1.5 since 18 months is 1.5 years. We substitute and find:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the answer is 99.
